摘要:Americans love their salty
snacks, but not especially the
lower fat versions. In 1999, Americans
purchased more than 1.6 billion
pounds of potato chips, pretzels,
and microwave popcorn from
supermarkets, drug stores, and
mass merchandising outlets. Sales
of these salty snacks increased 6
percent from 1995 to 1999. Sales
of regular versions increased 11
percent between 1995 and 1999,
while sales of lower fat versions
decreased 6 percent in the same
period.
